Fast Neutron Detector Based on Hybrid 2D Perovskite Thin Films

open access: yesAdvanced Functional Materials, Volume 35, Issue 46, November 12, 2025.
This work presents the direct detection of fast neutrons using flexible hybrid 2D perovskite (PEA2PbBr4) thin‐film detectors. Thanks to their high low‐Z elements content and good charge transport, these materials enable efficient neutron detection. The thin film configuration allowed the operation at low voltage, and offer scalability, flexibility, and

A Study on the Line of Sight to Galaxies Detected at Gamma-Ray Energies

open access: yesThe Astrophysical Journal Letters
The large-scale universal structure comprises strands of dark matter and galaxies with large underdense volumes known as voids. We measure the fraction of the line of sight that intersects voids for active galactic nuclei (AGN) detected by Fermi Large ...

Chemo‐Mechanical Coupling in Hydrogels: Dynamics in the Diffusion‐Limited Regime

open access: yesAdvanced Functional Materials, Volume 35, Issue 47, November 19, 2025.
A time‐dependent continuum model is developed to capture the transient swelling dynamics of chemo‐mechanical hydrogels. By coupling chemical reactions, solvent transport, and polymer deformation, volume phase transitions, reaction kinetics, and transient mechanical instabilities are analyzed.

State‐of‐the‐Art Solar Blind and X‐Ray Photodetectors Based on Gallium Oxide

open access: yesAdvanced Photonics Research, Volume 6, Issue 11, November 2025.
State‐of‐the‐art Ga2O3‐based solar‐blind UV and X‐ray photodetectors (PDs) are reviewed. Benchmark plots compare responsivity versus specific detectivity for UV PDs (photoconductors, photovoltaic, Schottky, heterojunction, avalanche, and phototransistor types) and sensitivity versus response time for X‐ray detectors based on Ga2O3 bulk crystals, thin ...

Broad Redox Density of States and S–O Functionalities Drive Stable Pseudocapacitive Behavior in Sulfurized Polyacrylonitrile (SPAN) Cathodes

open access: yesAdvanced Science, Volume 12, Issue 43, November 20, 2025.
We report a fundamental mechanism underlying charge storage in sulfurized polyacrylonitrile cathodes. Stable sulfuroxygen groups and a broad redox density of states enable pseudocapacitive behavior distinct from conventional sulfur cathodes. Through combined spectroscopic and electrochemical analysis, this study reveals key structurefunction ...
